[TRS-80]

rockpro64 download page has a looking for maintainer

Many things are still in flux in the project, due to recent changes.  After all the dust settles, some of these other things will end up getting updated, eventually, I am sure.

what really makes me think list is not up to date is that there have been no builds uploaded since last year while other boards started having new uploads early this month (02/2022) [...] already root directories from apt have been erased from the apt libraries

I can assure you that list is the most up to date information available.

Everything else you are mentioning is a function of the target being removed from the automated build system (which sounds like it may have been done some time ago, if what you are saying is correct).  However, as always, it is still possible to build your own images.  It's not even that hard, actually.

Armbian has always been, first and foremost, a build tool after all.  The fact that they/we publish images is just a secondary convenience for users.  But that was one of main things which was re-evaluated recently.
